ELECTRIC APPLIANCE.

Specification of'Letters Patent.

Patented Jan. 9,1912.

Application filed April 1, 1910. Serial No. 552,890.

To all whom it may concern:

Be it known that I, MARTIN THULIN, a citizen of the United States,residing at Ephraim, in the county of Sanpete and State of Utah, haveinvented new and useful Improvements in Electric Appliances, of whichthe following is a specification.

The invention relates to an improved means for delivering an electriccurrent to a patient for remedial effect, and more particularly improvedhandles forming the terminals of the respective conductors.

The main object of the present invention is the provision of a handlefor electromedical use constructed to permit the application of aconductor thereto in a simple and effective manner and made up of anon-conducting material to prevent the passage of the current to thepatient except following the initial treatment of the handles.

The invention in its preferred details of construction will be describedin the following specification, reference being had par-. ticularly t0the accompanying drawings, in which Figure 1 is a perspective view ofthe device complete. Fig. 2 is a longitudinal sectional view of one ofthe handles. Fig. 3 is a perspective view of the closing plug.

Referring particularly to the accompanying drawings, the improved deviceincludes in its conventional featuresaplugl designed for connection toany energized socket, from which plug extend conductors 2 and 3 of anyapproved type. The terminals of the conductors are provided with handles4 of identical construction, which handles form the novel feature of thepresent invention.

The handle 4: is centrally formed with a bore 5 which, adjacent whatwill be termed the forward or free end of the handle, iscircumferentially enlarged, forming a recess 6 of materially greaterdiameter than the bore 5. The conductor terminal is preferably providedwith a metallic body 7 having a size and shape corresponding with thesimilar dimensions of the channel 6 except that said body is of lesslength than the channel. The bore 5 is of a size to more or less looselyreceive a conductor, while the body 7 fits more or less snugly in thechannel. The body 7, which is preferably a metallic conductor, thusforms one of the terminals, and when in place, as shown in Fig. 2, theyprevent endwise movement of the conductor relative to the handle in onedirection. That portion of the channel 6 in advance of the forward endof the body 7 is to be closed by a plug 8, snugly seating within thesame and preferably bearing against the end of the body. The plug isformed on its peripheral surface with a series of longitudinal grooves 9which, when the plug is in place, form a series of openings between thesurface of the plug and the inner surface of the channel 6.

In use, with the plug connected in the socket, the free ends of thehandles are dipped in the water, or if desired in any other medicinalliquid. Such liquid will thus fill the grooves 9 in the plug,establishing a path of conductivity between the body 7 and the hand orother portion of the patient. By this means the medicine is used as aconductor, and will therefore have increased efi'ect in conjunction withthe electric current. A small quantity only of the liquid is used andthe presence or absence of the same may be readily determined by thepresence or absence of the current to the patient, as in the absence ofthe liquid in the grooves 9 no current whatever will pass to thepatient, as the handles and plug are of a non-conducting material.

The device has been found particularly efficacious in the treatment ofrheumatism or the like in which one of the handles is brought intocontact with the foot of the patient and the other grasped by the hand.

Having thus described the invention, what I claim as new, is

An electrode for electro-medical use comprising a non-conductive casingof uniform diameter having a bore loosely receiving a conductor, and aCounter-bore snugly receiving an enlarged conductor terminal, a plug inthe outer end of the counter-bore retaining said terminal againstmovement within the said casing, said plug having liquid-receivinggrooves extending longitudinally from the enlarged conductor terminal tothe exterior of the electrode.

In testimony whereof I aflix my signature in presence of two witnesses.

MARTIN THULIN.
